Abstract
The invention discloses a production method of a filter. The method includes the steps that firstly, soft PU adhesives with the shore A hardness being 5-30 degrees are selected and injected into a mold so that soft PU sealing pieces can be obtained; secondly, hard PU adhesives with the shore D hardness being 35-60 degrees are selected and injected into an upper end cover mold so that a hard PU upper end cover can be manufactured; thirdly, a protective net and filter paper are inserted into the hard PU upper end cover mold together, the protective net, filter paper and the hard PU adhesives are formed together so that a semi-finished product can be manufactured, the upper portion of a filter element is manufactured after the hard PU adhesives are foamed and cured for 2-8 minutes, and the upper end cover mold is pulled out; and fourthly, hard PU adhesives with the shore D hardness being 35-60 degrees are selected and injected into a lower end cover mold so that a hard PU lower end cover can be manufactured, the semi-finished product obtained in the third step is inserted in the lower end cover mold, the lower end cover mold is pulled out after the hard PU adhesives are foamed and cured for 2-8 minutes, the filter element is manufactured, and manufacturing is finished. The production method not only simplifies the manufacturing technology and reduces cost but also is beneficial for environmental protection.
Description
Technical field
The present invention relates to cleaner, particularly relate to a kind of production method of cleaner.
Background technology
As shown in Figure 1, the production method of current cleaner comprises following operation:
Operation 1: use mould molding to obtain upper end cover 3, the bottom end cover 8 of plated steel sheet material on punch press;
Operation 2: bonding agent 4 is injected inside upper end cover 3, filter paper 5, protecting wire net 6 are inserted inside upper end cover 3 together, shaping together with bonding agent 4, bonding agent 4 solidifies more than 10min and enters next procedure simultaneously;
Operation 4: bonding agent 7 is injected inside bottom end cover 8, inserts the semi-finished product that operation 2 obtains inside bottom end cover 8, shaping together with bonding agent 7, and bonding agent solidification more than 10min enters next procedure;
Operation 5: use bonding agent 2 bonding with seal 1 semi-finished product that operation 3 obtains, obtain filter core 9, bonding agent solidification more than 5min, filter core manufacturing process completes.
Existing production method has following defect: (1), the parts upper end cover 3 of operation 1 production, bottom end cover 8 need making to overlap metal die more, Mold Making costly, and part making need be completed in multiple operation, production process is many, exist in goods turnover operation, production efficiency is low, and cost of labor is high; (2), operation 2, operation 3, the bonding glue of operation 4 all needs to wait for that bonding agent solidifies completely, bonding firmly after could next step operation, the stand-by period is long, and production efficiency is low; (3), this technique need in punching press post, post, 2, injecting glue post completes, and increases operating personnel, increases cost of labor, need have enough to meet the need semi-finished product, reduces production efficiency; (4), after filter core is finished using, end cap, bonding agent are difficult to process, are unfavorable for environmental protection.
Summary of the invention
Technical problem to be solved by this invention is: the production method providing a kind of cleaner, not only simplify manufacture craft, reduces cost, and is beneficial to environmental protection.
For solving the problems of the technologies described above, the present invention proposes a kind of production method of cleaner, comprising the steps:
Step one, selection Shore A hardness is the soft PU glue of 5 ° to 30 °, injects mould and obtains soft PU seal;
Step 2, selection shore D hardness is that the hard PU glue of 35 ° to 60 ° injects upper end cover mold, makes hard PU upper end cover;
Step 3, inserts protecting wire net, filter paper in hard PU upper end cover mold together, shapingly together with hard PU glue makes semi-finished product, treats that hard PU glue foamed solidification completes filter core upper part after 2 to 8 minutes and makes, extracts upper end cover mold;
Step 4, selects shore D hardness to be in the hard PU glue injection bottom end cover mould of 35 ° to 60 °, makes hard PU bottom end cover, the semi-finished product that step 3 obtains are inserted in bottom end cover mould, treat that hard PU glue foamed solidification extracts bottom end cover mould in 2 to 8 minutes afterwards, make filter core, complete making.
Further, the described hard PU glue foamed solidification time is 5 minutes.
Technique scheme at least has following beneficial effect:
(1) the present invention only need make upper and lower end cap mould of plastics, reduces Mold Making cost;
(2) the present invention meets upper end sealing simultaneously, is connect on each part limit and is integrated, realize the filtration sealing property of product;
(3) whole assembly technology only need on a post complete operation, reduce operating personnel, reduce cost of labor, and in manufacturing process semi-finished product do not need turnover, enhance productivity;
(4) the soft PU seal in the present invention belongs to self-made components, and the seal in more existing technique belongs to outsourcing piece, reduces material cost, management cost;
(5) the hard PU upper end cover in the present invention and hard PU bottom end cover replace plated steel sheet end cap, manufacture craft is easy, safety, environmental protection;
(6) after improving, technique does not need the bonding filter paper of bonding agent, protecting wire net, saves material cost;
(7) cap material belongs to glue class material, and filter core easily processes after finishing using, and is beneficial to environmental protection.
Accompanying drawing explanation
Fig. 1 is the structural representation of filter core in prior art.
Fig. 2 is the structural representation of filter core in the production method of cleaner of the present invention.
Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below in conjunction with accompanying drawing, the present invention is described further.
As shown in Figure 2, the production method of cleaner of the present invention comprises the following steps:
Step one, selection Shore A hardness is the soft PU glue of 5 ° to 30 °, injects mould and obtains soft PU seal 10;
Step 2, selection shore D hardness is that the hard PU glue of 35 ° to 60 ° injects upper end cover mold, makes hard PU upper end cover 20;
Step 3, inserts protecting wire net 30, filter paper 40 in hard PU upper end cover mold together, shapingly together with hard PU glue makes semi-finished product, treats that hard PU glue foamed solidification completes filter core upper part after 5 minutes and makes, extracts upper end cover mold;
